[Work] vision talk

Today Thomas Vetter gave a talk about recent development of morphable model.
The talk is kind of boring. (For general audience, I will say it is quite good.)
It does, however, convey some essence of doing computer vision research.
All most all the computer vision problems look like pretty easy at first glance. But after your serious thinking and investigation, you will find most of the "naive" problems are quite difficult.
A typical approach to these problems is first to define and clarify the problem. Second, we need to build an efficient mathematical model for the problem. Third, we try to solve the problem. Finally, we should test the method with both synthetic and real data.
